I don't see anything on the schedule right now. With there only being a few weeks between Easter / Spring Break time and the start of the DL 50th anniversary celebration, there may not be any rehabs scheduled for that period. It's not an attraction, but apparently the Garden Grill restaurant (currently closed) will not re-open until July.
The popular rumors for upcoming attraction rehabs are the Haunted Mansion and Pirates of the Caribbean. But, even if true, it could be the Fall before they go down.
"Seasonal" attractions like the Wonders of Life pavilion at Epcot and The Timekeeper are likely to be closed.
